I updated 2 days ago and my webcam stopped working.

  • The following softwares do not detect my built-in webcam:
    • Zoom
    • Discord
    • Chromium
  • /dev/video is not present.
  • /dev/video0 is not present.
  • The camera works fine in MS Windows.

I've tried:

  • Rebooting
  • Reinstalling v4l2loopback-dkms and rebooting
  • sudo modprobe v4l2loopback
    • This creates /dev/video0 corresponding to a dummy video device.
  • sudo modprobe -r uvcvideo && sudo modprobe uvcvideo

Details:

  • Laptop: ThinkPad P14s
  • Kernel: 5.13.4-arch2-1

Does anyone have a clue how I can go about fixing my laptop's built-in webcam?

A comment on Reddit r/archlinux suggested to install a firmware-update for the USB host controller like upd72020x-fw (Renesas uPD720201 / uPD720202 USB 3.0 chipsets firmware):

For the Webcam issue on ThinkPad P14s, some said (read it on r/thinkpad but can't remember which post) to use this driver from AUR:

https://aur.archlinux.org/packages/upd72020x-fw/

Screen tearing, suspend/hibernate issues are usually related to graphic card driver. Blacklisting the discrete graphic card might just solve the issue.

After the firmware-update my issue was fixed.

For other users experiencing a similar problem, I suggest looking to see if there are alternative drivers that are more suited for your setup.
